To a 100-mL round-bottomed flask was added ethyl N-(tert-butoxycarbonyl)glycyl-3-(6-methoxy-2-pyridinyl)alaninate (1.28 g, 3.36 mmol) and trifluoroacetic acid (5 mL, 67.3 mmol) in DCM (5 mL). The reaction mixture was stirred at room temperature for 3 h. The solvent was removed in vacuo to give the crude ethyl glycyl-3-(6-methoxy-2-pyridinyl)alaninate as a colorless viscous oil, which was used without purification.
